Ecosystems Research

Roger A. Burke

My recent research has involved relating watershed land use to stream biogeochemical characteristics, including measurements of stable isotope ratios of dissolved organic and inorganic carbon; trace gas (CO2 and N20) concentrations; and sediment denitrification enzyme activity (DEA). This work took place in headwater streams of the Georgia Piedmont that are impacted by poultry and cattle production, and in Appalachian headwater streams impacted by mountaintop mining.  Future work will involve using 15N-labeling techniques to estimate denitrification rates in Georgia Piedmont headwater streams.
